Logarithmic axis uses logarithmic scale and it is very useful in visualizing when the data has values with both lower order of magnitude (eg: 10^-6) and higher order of magnitude (eg: 10^6).
To render Logarithmic axis, set valueType to Logarithmic.
Tooltip is enabled in this example, to see the tooltip in action, while the selected range is changed.
